Info

Pressure RegulatorThe Pressure Regulator consists of a manual pressure regulator and a pressure gaugemounted on the control panel. The regulator maintains the proper back pressure on themembrane.Control PanelThe Control Panel permits operation and monitoring of the system from a convenientlocation such as in the living quarter of a boat.Feedwater PumpThe Pre-feed pump consists of a separate relay controlled pump that forces feed-waterthrough the pre-filters. Installation of a feed-water pump will decrease pre-filtermaintenance, system noise and vibration and RO pressure pump wear. If either the engineor the Pre-Filtration Module must be mounted more than two feet above the feed-watersource level, a Feed-water Pump Module will be required as well as a check valve. A FeedwaterPump Module is recommended for all installations.Emulsion Removal Module (ERM) OptionalThis unit removes oil or silt from the feed-water, to further protect the RO membrane. Thiselement should be replaced as soon as oil is detected or every year during normalservicing.Plankton Filter Assembly OptionalThis is a 50-micron SS element that works more efficiently than the sea strainer and neverneeds to be replaced -- just cleaned on a normal basis. This will not replace a sea strainer.Ultraviolet/Charcoal Sterilizer OptionalAlthough the RO process is very effective at removing bacteria and other pathogens fromthe feed water, a UV/Charcoal Sterilizer can be added that will function as a second line ofdefense against any micro-organisms that may have penetrated the RO membrane. The UVSterilizer is recommended anytime the desalinator is going to be used in brackish orsewage contaminated waters. The charcoal element removes foul odors and tastes in theproduct water. The charcoal filter is rated at .5 micron and should be replaced every year.It is a special style charcoal filter, call Balmar for replacement. The UV bulb should bereplaced every 2000 hrs. or every two years. After recommended replacement time, thespectrum of the light will shift and cause insufficient radiation of the bacteria and viruses.Supplemental FiltersA 5 micron filter is standard with the Aqua-Pac. 5 and10 micron filters are available in thestandard size. Larger surface area filters are also available in various micron sizes. Mediafilters are available for land based or commercial applications.Freshwater Flush Assembly OptionalThis is a charcoal filter and three-way valve assembly designed to be installed onto thefresh water system for flushing the salt water out of the desalinator. Not intended for longshut down periods. Up to one month before re-flushing is required.- 11 -
Watermaker SpecificationsFeed-water pH Range: 3-11Feed-water Temperature Range: 40° to 100°F (4.4°C to 37.8°C)Membrane Salt Rejection: 98.6 % or greaterMaximum Operating Pressure: 800 PSICpm Switched Accessory Terminal Output: 6 Amps @ 12 VDCHigh Pressure Pump Crankcase Lubricant: Balmar P/N 334-010High Pressure Pump Crankcase Capacity: 12 oz*All performance specifications are with feed-water salinity of 35,000 PPM, feed-water pH of 8, feed-watertemperature of 77°F (25°C), and operating pressure of 800 PSI. Product water output will decrease with lower feedwatertemperatures. Rated output at a given temperature is +/- 15%.Replacement PartsGenuine Balmar replacement parts as well as modules and accessories are available fromauthorized Balmar dealers. As a convenience to Balmar product users, replacement partsare also available directly from Balmar Products.WARNING: Use of other than genuine Balmar replacement parts may impair theperformance and/or inherent safety of the system and may also void the warranty.Replacement parts obtained from dealers are not necessarily genuine.Desalinator OperationInitial Watermaker StartupNOTE: If there is a chance that the ROM will be subjected to freezing temperatures duringthe lay-up, remove the high pressure vessel, seal the vessel ports with the caps suppliedin the Cleaning/Biocide Kit, and place the vessel in a storage location whose temperaturewill be maintained between 50°F (10°C) and 75 °F (24°C). A food grade preservative isavailable from Balmar, should removal be difficult. This acts as an appropriate anti freeze.But it is not rated below 20 F.CAUTION: Allowing the membrane to freeze will cause permanent damage.The following procedure should be used for new installations and for returning systemsto service after a prolonged shutdown.1. De-energize the Desalinator circuit breaker. Ensure that there are no explosivevapors present in any of the compartments where components of the Desalinatorare located. (This step is primarily for installation in hazardous locations such asoffshore oil platforms and gasoline powered boats.)2. Ensure that the high-pressure pump crankcase is filled to the red dot on the oillevel indicator.3. Set the Product Water Control valve to normal.4. Open all feed-water inlets.- 12 -
